Also stayed at Villa Alpen at Sun Valley (Shiga Kogen Sun Valley) in 2010 and going back in 2011. I can add a few things:-
Distance to ticket office :- 20m
Distance to lift 30m
Excellent food at Villa Alpen. Captain and his family will ensure you have a great stay.
Onsen in lodge great for relaxing in.
You can either ski your way over to the other resorts or, if you're in a rush, you can take the free bus up to the other ski-areas.

Stayed at Villa Alpen (Shiga Kogen Sun Valley): very friendly. The resort, however, is on the edge of Shiga Kogen and takes about 2 hours in lifts to reach the other side.
Sun Valley is more suited for beginner/intermediate.
Great for kids and wide open slopes.
Not many place to buy food. More options for resturants at Ichonise family ski runs.
Overall, Shiga Kogen (Shiga Kogen Sun Valley) is a huge place and just great!!!
